WebbProtons have the unique ability to stop at a defined range, therefore have: 1. REDUCED EXIT DOSE 2. Increase dose to target volume 3. Improved local control 4. Improved survival … Webb20 maj 2024 · A proton is one of three main particles that make up the atom. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. …
WebbProtons and neutrons are in the center of the atom, and they make up the nucleus. Protons have a positive charge. Neutrons have a neutral charge (no charge). Electrons have a negative charge, and are far away from the nucleus. The charge on the proton and electron are exactly the same in magnitude, but opposite in sign.
